  - qualifyIndexName
```
public boolean qualifyIndexName()
```
    RDMS does not support qualifying index names with the schema name.
    Do we need to qualify index names with the schema name?
    
    覆盖:
    
    qualifyIndexName 在类中 Dialect
    
    返回:
    
    boolean
  - forUpdateOfColumns
```
public boolean forUpdateOfColumns()
```
    The RDMS DB supports the 'FOR UPDATE OF' clause. However, the RDMS-JDBC driver does not support this feature, so a false is return. The base dialect also returns a false, but we will leave this over-ride in to make sure it stays false.
    Is FOR UPDATE OF syntax supported?
    
    覆盖:
    
    forUpdateOfColumns 在类中 Dialect
    
    返回:
    
    True if the database supports FOR UPDATE OF syntax; false otherwise.
  - getForUpdateString
```
public String getForUpdateString()
```
    Since the RDMS-JDBC driver does not support for updates, this string is set to an empty string. Whenever, the driver does support this feature, the returned string should be " FOR UPDATE OF". Note that RDMS does not support the string 'FOR UPDATE' string.
    Get the string to append to SELECT statements to acquire locks for this dialect.
    
    覆盖:
    
    getForUpdateString 在类中 Dialect
    
    返回:
    
    The appropriate FOR UPDATE clause string.
  - supportsCascadeDelete
```
public boolean supportsCascadeDelete()
```
    RDMS does not support Cascade Deletes. Need to review this in the future when support is provided.
    Does this dialect support cascaded delete on foreign key definitions?
    
    覆盖:
    
    supportsCascadeDelete 在类中 Dialect
    
    返回:
    
    true indicates that the dialect does support cascaded delete on foreign keys.
  - supportsOuterJoinForUpdate
```
public boolean supportsOuterJoinForUpdate()
```
    Currently, RDMS-JDBC does not support ForUpdate. Need to review this in the future when support is provided.
    Does this dialect support FOR UPDATE in conjunction with outer joined rows?
    
    覆盖:
    
    supportsOuterJoinForUpdate 在类中 Dialect
    
    返回:
    
    True if outer joined rows can be locked via FOR UPDATE.
  - getAddColumnString

    返回:
    
    String
  - supportsSequences
```
public boolean supportsSequences()
```
    从类复制的说明: Dialect
    
    Does this dialect support sequences?
    
    覆盖:
    
    supportsSequences 在类中 Dialect
    
    返回:
    
    True if sequences supported; false otherwise.
  - getSequenceNextValString
```
public String getSequenceNextValString(String sequenceName)
```
    从类复制的说明: Dialect
    
    Generate the appropriate select statement to to retrieve the next value of a sequence.
    This should be a "stand alone" select statement.
    
    覆盖:
    
    getSequenceNextValString 在类中 Dialect
    
    参数:
    
    sequenceName - the name of the sequence
    
    返回:
    
    String The "nextval" select string.
  - getCreateSequenceString
```
public String getCreateSequenceString(String sequenceName)
```
    从类复制的说明: Dialect
    
    Typically dialects which support sequences can create a sequence with a single command. This is convenience form of Dialect.getCreateSequenceStrings(java.lang.String) to help facilitate that.
    Dialects which support sequences and can create a sequence in a single command need *only* override this method. Dialects which support sequences but require multiple commands to create a sequence should instead override Dialect.getCreateSequenceStrings(java.lang.String).
